FC17 server is not accepting connections from ssh and other

http://forums.fedoraforum.org –
Hello i run Fedora 17 x86 on my machine
I have also other servers like Centos and Fedora 16 and imacs
I want to have a normal functioning network
From my other fedora 16 server or my Mac i get this error while the openssh is running and is not firewalled, iptables is off and flushed (iptables -Z -F )
this happens all the time after retrying 10 or 20 times (random) i can connect.
ssh [email protected]
ssh: connect to host 192.168.123.34 port 22: Connection refused
(service is running)
